SoundCloud

Create, record and share the sounds you create with anyone using SoundCloud, the world's largest community of sound creators.

Recording and uploading sounds to SoundCloud lets people easily share them privately with their friends or publicly to blogs, sites and social networks. It takes just a click to share sounds to Twitter, Tumblr, Facebook and Foursquare.
SoundCloud can be accessed anywhere using the official iPhone and Android apps, as well as hundreds of creation and sharing apps built on the SoundCloud platform.
SoundCloud offers free accounts to every amateur creator, with more advanced users able to upgrade to premium accounts for advanced features like statistics, controlled distribution and custom branding.
